ROBERT F. SIMMONS, OF ATTLEBOROUGH FALLS, MASSACHUSETTS.

MANUFACTURE OF JEWELRY-CHAINS.

SPECIFICATION forming part of Letters Patent No. 225,879, dated March23, 1880,

Application filed J nly 19, 1879.

To all whom it may concern:

Be it known that I, Bonner F. SiMMoNs, of Attleborough Falls, in thecounty of Bristol and State ofMassachusetts, have invented certain newand useful Improvements in the Manufacture of J ewelry'Ohains, of whichthe following is a specification.

My invention particularly relates to chains of the kind known ascombination link chains 5 and its object is to produce a simple, strong,and durable chain of fine appearance.

My invention consists in a combination chainlink, comprising twoopposite sides and ends, formed from a single blank or piece of metal,and separatepieces forming the intermediate sides, the said blank orpiece having projections extending transversely from its opposite edges,made in the same piece with it and bent so as to form hollow cap-likeends, and the whole being organized and combined so that theintermediate sides are embraced and held in place by the hollow cap-likeends of the link.

It also consists in novel forms of blanks from which said chain-linksare formed.

In the accompanying drawings, Figures 1, 2, and 3 are face views of aplate-metal blank from which two opposite sides and cap like ends of alink are to be formed, showing the same at different stages of itsmanufacture. Fig. 4 is a perspective view of the blank ready to be benttransversely to form the ends and sides. Figs. 5 and 6 are face views ofthe pieces intended to form two sides of the link. Fig. 7 is an edgeView thereof. Fig. Sis a side view .of a spiral ornament intended to besecured in the center of the link. Fig. 9 is a side view of the blank,showing the same partially bent and the manner of securing the looseside pieces in position; and Fig. 10 is a side view of a finished link.

Similar letters of reference designate corresponding parts in all thefigures.

Although the parts of which my chain-link is composed may be otherwiseformed, I prefer to cut the blanks from strips of metal 'already platedin any suitable manner, prefera= bly by soldering thereto a thin sheetofprecious metal. I A, Fig. 1, designates one of the blanks thus formed,which may be of any suitable pattern. The blank is provided upon itsedges with projections a, extending transversely from and made in thesame piece with it, which are adapted to be turned up at right angles tothe: body, forming cap-like ends, as shown in Fig.

10, and which may secure in place separate pieces or bars, forming twosides of the chainlink. The blank thus formed may be as represented inFig. 1, or it may be perforated by means of suitable cutters, asillustrated in Fig. 2, and formed as shown in Fig. 9.

I preferably out channels or grooves bin the blank, to facilitate thebending of the projections at, and these channels may have beveledsides, so that a miter-joint may be formed on turning the projectionsover, as represented in Fig. 4.

The blank A is preferably of sufificient length to form two oppositesides of a link, the blank being bent transversely at the dotted line f,Fig. 1, and the portion from fto g forming one side of the link.

B, Fig. 8, designates a spiral ornament, which may be placed in thecenter of the link, to add to its appearance and to stay or brace thesame.

0 (see Figs. 5, 6, and 7) designates side pieces, which may be cut froma strip of plated metal similar to the blanks A, and which may be formedas represented in Fig. 7 or left plain. The method of fastening theseside pieces, G,in position is clearly illustrated in Figs. 9 and 10. Theprojections a, together with the body of the blank, form, when bent intothe position shown in Fig. 10, hollow caplike ends, and as the ends ofthe side pieces,

0, extend into these ends, they are securely held in position. Theseveral parts forming the link being placed in position, as shown inFig. 9, the blank A is bent into the form represented in Fig. 10, andmay, if desirable, be fastened by soldering at c.

D designates rings, of which any number may be employed, for connectingthe links to form a chain, and which are represented as passing throughperforations d in the links.

It will be seen that as two sides and the ends of the links may beformed from a single piece of metal, which serves to secure all theother parts of the link in position, and as only such parts of the linkas are exposed need be plated, chains may be made in this manner andtherefore I disclaim what is shown therein.-

What I claim as my invention, and desire to secure by Letters Patent,is-

1. Acoin bination chain-link, comprising two opposite sides and ends,formed from a single blank or piece of metal, and separate piecesforming the intermediate sides, the said blank or piece havingprojections extending transversely from its opposite edges, made in thesame piece with it and bent so as to form hollow cap-like ends, and theWhole being organized and combined so that the intermediate sides are0ll'lbl2LC6d and held in place by the hollow cap'like ends of the link,substantially as specified.

2. As an improvement in blanks from which to manufacture ornamentalchain-links, the form or shape of the double blank described, andrepresented in Fig. 1.

3. As an improvement in blanks from which to manufacture ornamentalchain-links, the form or shape of the single blank described, andrepresented in Fig. 1 from letters f to g.
